By the end, you’ll have a thorough understanding of how blue cheeses are made, from milk to the final product.
The Origins of Blue Cheese
Before we delve into the production process, it’s essential to understand the background of blue cheese. The origins of blue cheese can be traced back to ancient times, with the earliest records dating back over a thousand years. Some of the most famous blue cheeses, such as Roquefort, Gorgonzola, and Stilton, have unique stories tied to their regions.
Roquefort, for example, hails from France and is made primarily from sheep’s milk, while Gorgonzola comes from Italy and is made from cow’s milk. Both have their distinct profiles, flavors, and textures, highlighting the diversity found within the blue cheese category.
The Fundamentals of Blue Cheese Making
Creating blue cheese involves several key stages, each critical to developing the desired characteristics of the final product. The process starts with selecting quality milk, followed by curdling, molding, and aging. Here’s a closer look at each step.
1. Selecting the Milk
The foundation of any cheese is its milk, and blue cheese is no exception. The type of milk significantly influences the flavor and texture of the cheese.
- Cow’s Milk: Typically used for Gorgonzola and Stilton, providing a creamy texture.
- Sheep’s Milk: Essential for Roquefort, delivering a rich and tangy profile.
- Goat’s Milk: Sometimes used for its unique flavor and characteristic tanginess.
The milk must be fresh and of high quality, as any contamination can affect the final product. Many artisan cheesemakers use milk sourced from specific farms where they can control the quality and ensure it meets their standards.
2. Curdling the Milk
Once the milk is collected, it undergoes a heating process to reach the ideal temperature, usually between 28-35°C (82-95°F), to facilitate the introduction of bacteria and rennet.
- Starter Culture: A mixture of bacteria is added to the warm milk. These bacteria not only kickstart the fermentation process but also assist in developing the cheese’s flavor and texture.
- Rennet: A natural enzyme derived from the stomach lining of ruminants is introduced to coagulate the milk.
The combination of bacteria and rennet causes the milk to curdle, forming curds and whey. The curds are then cut into smaller pieces to help separate them from the whey.
3. Molding the Cheese
After the curds have formed, they are drained of excess whey and placed into molds. This step is crucial because the shape and size of the mold will directly influence the cheese’s final texture and aesthetics.
- Pressing: The curds are lightly pressed to compact them, but unlike other cheeses, blue cheese requires less pressure. This helps maintain a certain moisture content that is crucial for the aging process.
4. Introducing Penicillium Roqueforti
What sets blue cheese apart from other types is the blue mold that gives it its distinctive look and flavor. The mold, known scientifically as Penicillium roqueforti, is either mixed into the curds during the molding stage or sprinkled onto the surface.
- The introduction of this mold is what creates the characteristic blue veins as the cheese ages. The mold grows throughout the cheese, breaking down proteins and fats, resulting in a creamy texture and sharp flavor.
5. Aging the Cheese
Aging, or affinage, is perhaps the most critical phase in blue cheese production. It influences not only the cheese’s flavor but also its aroma and texture.
- Humidity and Temperature: Blue cheese is typically aged in environments with high humidity (around 80-90%) and a controlled temperature (around 10-12°C or 50-54°F). These conditions encourage the growth of the blue mold and contribute to a moist texture.
Aging periods can vary significantly depending on the type of blue cheese:
- Roquefort: Aged for around 3-5 months.
- Gorgonzola: Ages for 3 to 12 months, developing varying flavors and intensities.
- Stilton: Typically aged for 9 months or more.
During the aging process, cheesemakers often pierce the cheese with stainless steel needles. This technique allows air to enter the cheese, promoting mold growth and enhancing the development of flavor and aroma.
The Importance of Terroir in Blue Cheese
One of the reasons blue cheese has such unique characteristics is the influence of terroir. Terroir refers to the environmental factors—such as soil composition, climate, and local traditions—that affect the characteristics of agricultural products, including cheese.
Geography: The region where the milk is sourced significantly affects the flavor profile of the cheese. For example, Roquefort cheese relies on the specific grasses and flowers that sheep graze in the regions of southern France.
Methodology: Traditional cheese-making techniques passed down through generations contribute to the authenticity of the product. Artisan cheesemakers often adhere to strict methods that reflect their cultural heritage.
The Varieties of Blue Cheese
Blue cheese comes in various styles and flavors. Here are a few notable examples:
1. Roquefort
A French blue cheese made from sheep’s milk, known for its creamy texture and tangy, bold flavor. Roquefort is aged in the caves of Roquefort-sur-Soulzon, where the specific environment aids its unique profile.
2. Gorgonzola
Originating from Italy, Gorgonzola can be creamy to crumbly, with a pungent aroma and sweet to sharp flavor, depending on the aging time. It is one of the oldest blue cheeses in the world.
3. Stilton
Stilton is a British blue cheese, richer and creamier, often enjoyed with desserts due to its somewhat fruity flavor. It is known for its distinct blue veins and crumbly texture.
Pairing Blue Cheese
Pairing blue cheese with other foods can enhance its bold flavors. Here are some classic pairing ideas:
- Fruits: Fresh or dried figs, pears, and apples complement the strong flavor of blue cheese.
- Nuts: Walnuts and pecans’ earthy taste works beautifully with the rich creaminess.
- Wines: Bold wines like Port, Sauternes, or Cabernet Sauvignon pair well, balancing the saltiness and intense taste of blue cheese.

What is blue cheese, and how is it different from other types of cheese?
Blue cheese is a distinct type of cheese characterized by its blue or green veins, which are created by the introduction of mold, specifically Penicillium roqueforti or Penicillium glaucum. These molds develop during the cheese-making process, giving blue cheese its unique flavor profile and aroma. Unlike other cheeses, which may be made from cow, goat, or sheep milk and left to age without specific mold cultures, blue cheese deliberately incorporates these molds, which contribute to its creamy texture and tangy taste.
In contrast to softer cheeses like Brie or hard ones like Parmesan, blue cheese has a crumbly yet creamy texture that can vary depending on the specific variety. Its strong, pungent flavor differentiates it from milder cheeses, making it a favorite for those who enjoy bold tastes in their culinary adventures. The process of creating blue cheese often involves additional steps of piercing the cheese with needles or skewers to allow air to enter, encouraging the growth of mold within the cheese itself.
What are the main steps in the blue cheese-making process?
The blue cheese-making process begins with curdling milk, which can be sourced from cows, goats, or sheep. This is done by adding starter cultures and rennet to warm milk, allowing it to coagulate and form curds. Once the curds have formed, they are cut into smaller pieces to release whey, and the curds are then cooked and stirred to achieve the desired consistency. After this, the curds are drained, and during this stage, specific blue mold cultures are added to the mixture.
Following the initial preparations, the cheese is then placed in molds and left to age. Aging is a critical aspect as it allows the blue mold to develop and infuse its distinct flavors into the cheese. Throughout the aging process, the cheese may be pierced to create holes that facilitate air circulation. This process encourages the growth of mold throughout the cheese, resulting in the characteristic marbling. Depending on the variety, the aging period can range from a few weeks to several months, with different factors influencing the resultant flavor and texture.
What types of milk are used to make blue cheese?
Blue cheese can be made from various types of milk, including cow, goat, and sheep milk. Each type of milk imparts unique flavors and textures to the cheese. Cow’s milk is the most common option, producing a mild flavor and creamy texture, while goat’s milk often results in a sharper, tangy flavor that is favored by many blue cheese enthusiasts. Sheep’s milk, on the other hand, tends to create a richer and slightly sweeter taste, offering a different mouthfeel and depth of flavor.
The choice of milk can greatly impact the diversity of blue cheesemaking. Different regions have their preferences; for instance, Roquefort is traditionally made from sheep’s milk, while Gorgonzola is made from cow’s milk. Additionally, variations among breeds and dietary factors of the animals can also influence the final product. Therefore, the selection of milk plays a significant role in defining the characteristics of blue cheese.
How does the aging process affect blue cheese flavor and texture?
The aging process is crucial for developing the flavor and texture of blue cheese. During this period, the cheese undergoes biochemical changes that enhance its richness and complexity. As the cheese matures, the molds introduced during production break down fats and proteins, which contributes to the development of robust flavors that can range from sharp and pungent to earthy and creamy. The length of aging also plays a significant role; longer aging typically results in stronger flavors and a drier, crumbly texture.
Additionally, the conditions under which blue cheese ages, including temperature, humidity, and airflow, further influence its final characteristics. For example, cheeses allowed to age in moist environments often develop distinct moist and creamy textures, while those in drier conditions may become firmer. The unique interactions between flavors and textures during the aging process help craft a cheese that is both complex and celebrated, making it a favorite among cheese lovers.
